The inverse error function is usually defined with domain (−1,1), and it is restricted to this domain in many computer algebra systems.

Since I defined what I meant by $\Phi$, and it only appeared as an auxiliary function in a small section, I didn't think it would much matter what I called it. Gauss–Kronrod rules Main article: Gauss–Kronrod quadrature formula If the interval [a, b] is subdivided, the Gauss evaluation points of the new subintervals never coincide with the previous evaluation points (except at Gaussian Quadratures and Orthogonal Polynomials", Numerical Recipes: The Art of Scientific Computing (3rd ed.), New York: Cambridge University Press, ISBN978-0-521-88068-8 Gil, Amparo; Segura, Javier; Temme, Nico M.

The idea underlying the proof is that, because of its sufficiently low degree, h(x) can be divided by p n ( x ) {\displaystyle p_ − 4(x)} to produce a quotient For Gaussian quadrature, see Gaussian integration.

We can write ∏ 1 ≤ j ≤ n j ≠ i ( x − x j ) = ∏ 1 ≤ j ≤ n ( x − x j ) Switching to polar coordinates then gives (4) (5) (6) There also exists a simple proof of this identity that does not require transformation to polar coordinates (Nicholas and Yates 1950).

Using the binomial theorem, to expand $\sqrt{1+2v/x^2}$, we get $$\frac1{\sqrt{2\pi}}\int_x^\infty e^{-t^2/2}\,\mathrm{d}t \sim\frac1{\sqrt{2\pi}}e^{-x^2/2}\sum_{k=0}^\infty\frac{(-1)^k(2k-1)!!}{x^{2k+1}}$$ where $(-1)!!=1$. Error estimates The error of a Gaussian quadrature rule can be stated as follows (Stoer & Bulirsch 2002, Thm3.6.24).
